Peirce's Law of Triviality: The Implementation of the Trivium of Logic, Rhetoric and Grammar. Basic Categories for Linguistics and Literature Studies from a Universal Semiotic Theory This article focuses on the aspects that refer to linguistics in the works of Charles S. Peirce. His pragmatic philosophy implemented many other sciences and among them is the traditional trivium of logic, grammar, and rhetoric, which Peirce divided into different kinds of logic, grammar, and rhetoric. While the impact of the work of Peirce (...) on theses sciences is weak, the integration of the sciences in his philosophy is interesting as a step in the history of science and his work is an example for ecclecticism and historism of science in the 19th century and the universalism of science deducted from a philosophy that uses the sign as an unitarian principle. Triple constructions are a very common feature in the writings of Peirce, and the trivium is an example of an academic construction Peirce implemented. (shrink)
